削梨法在小瞳孔白内障超声乳化术中的应用

The application of featheredging pear(tangent remotion) method for phacoemulsifieation through a small pupil

目的 :探讨小瞳孔状态下应用削梨法超声乳化的手术技巧和注意事项。 方法:应用削梨法超声乳化技术对 69例 (78只眼 )小瞳孔白内障行超声乳化。 结果:无虹膜后粘连 63只眼 ,术后全部瞳孔恢复原状 ;15只眼分离粘连机化膜后应用削梨法进行超声乳化 ,术后 13只眼基本恢复圆瞳孔 ,2只眼瞳孔不规则。术后 3个月裸眼视力≥ 0 .5者 43只眼 (5 5 .13 % ) ,矫正视力≥ 0 .5者 61只眼 (78.2 1% )。 结论 :削梨法受瞳孔大小的限制较小 ,大大降低了手术操作的难度 ,减少了手术的危险性 ,不失为小瞳孔白内障超声乳化的好办法。

Objective:To discuss the surgical techniques and attention points in tangent remotion method for phacoemulsifieation through a small pupil. Method:78 eyes of 69 patients were emulsified by using tangent remotion method. Results:The 63 eyes without posterior synechia of the iris, after the surgery, all the pupils were recovered to normal size. In 15 eyes, the procedure using tangent remotion was performed after separation of synechia, after the surgery, a round pupil was obtained in 13 cases and an irregular pupil in 2 cases. The visual acuity at postoperative 3 month was ≥0.5 in 43 eyes (55.13%) and corrected ≥0.5 in 61 eyes (78.21%).Conclusion:The method using tangent remotion may less restrained the doctor from Phaeoemulsification through a small pupil. The difficult degree were greatly reduced, and the risk was reduced too. So it is the best method for phaeoemulsifieation through a small pupil.
